"The time to act is now. We need a national, concerted effort to prevent additional cases of type 2 diabetes in our nation - and we need it now. We have the scientific evidence and we've built the infrastructure to do something about it, but far too few people know they have prediabetes and that they can take action to prevent or delay developing type 2 diabetes," said Ann Albright, director of CDC's Division of Diabetes Translation.
CDC and the AMA, have taken efforts to develop a toolkit to help health care providers screen and refer high-risk patients to area diabetes prevention programs. The toolkit and other prevention information is available online, and there is also an online screening toolkit for patients to help them determine their type 2 diabetes risk.
Nearly 80,000 adults from the Adventist Health Study 2 completed food-frequency questionnaires at baseline and then were divided into five dietary groups: vegan (8% of the population), lacto-ovo vegetarian (29%), pesco-vegetarian (10%), semi-vegetarian (6%), and non-vegetarian (48%).
During 7 years' follow-up, researchers documented 490 cases of colorectal cancer. Compared with non-vegetarians, all vegetarians combined had a significantly reduced risk for colorectal cancer (adjusted hazard ratio, 0.78). When examined by type of vegetarian diet, only pesco-vegetarians had a significant reduction in risk (hazard ratio, 0.57).
"The evidence that vegetarian diets ... may be associated with a reduced risk of colorectal cancer, along with prior evidence of the potential reduced risk of obesity, hypertension, diabetes, and mortality, should be considered carefully in making dietary choices and in giving dietary guidance," the authors conclude.
